| Primary Purpose | Optimisation of the development corridor from today till 2050 under political boundaries like co2 emission targets, emission certificate prices (that are set in the framework) Standard parametrisation of several European countries Operation and unit dispatch on hourly basis of the whole optimisation time span Time series for Renewable Energy Generation with support for lookup table to simulate location details of optimal generator locations (wind) or less optimal sites. Flexibility of model settings to investigate targeted time span based on existing components, new investments, green field. Operation on hourly basis, but flexible adaptions can be implemented Investigation of need for long term, seasonal storage, synergies of renewable generation with different storage types. Investigation of policy effects on system structure like co2 emission allowance cost development trajectories, phase out of technologies, retarded investment incentives on certain technologies Investigation of reserve requirement, additional cost from grid expansion Investigation of sector electrification, additional system extension in case of higher demand and changed profiles |
| Primary Outputs | Optimal system transition / system configuration (and development) for the target time span based on parametrisation of today existing power plants - Averaged cost of electricity, cost of electricity per source per country per year based on input data (cost of investment & fuels) - Investment amount per year of all considered technologies in the focus years (e.g. 2015-2050) - Cost of investments of all components, cost of operation - operation of system components, utilisation of generation units for demand balancing |

| Changes in efficiency | Efficiency of a powerplant is set by investment year (technology based), efficiency(t) can be varied Application of serveral powerplant capacities together uses a weighted average mean trying to priorise higher efficiencies. | ||||||

| Comment on geographic (spatial) resolution | GENESYS is typically applied on a set of countries with NTC connections and aggregated capacities, it was has also been applied with regional/NUT3 parametrisation as a test. Aggregation of geospatial area to a specific zone allows flexible representation of states, tso regions, federal states or regions based on the availability of input data (e.g. capacities per zone, time series for RE geneators and load) | ||||||

| further properties | Specific targets can be set for limitation of annual Co2 Emissions per country/region or on a global scale, alternatively the competitiveness for thermal power generation can be evaluated under influence of co2 emission certificate price development assumptions Model can easily be adapted given the case input data can be provided for the representation of regions (time series, demand and existing system components) |
| Model specific properties | Model can calculate a fast system operation/unit dispatch in 1-2 minutes for 35 years on hourly basis (1 CPU) This can be implemented in an evolution strategy, genetic algorithm or monte carlo simulation/optimisation and it is suitable for multi-core operation (via openmp) |
